Nabokov's fourth novel, "The Eye" is as much a farcical detective story as it is a profoundly refractive tale about the vicissitudes of identities and appearances. Nabokov's protagonist, Smurov, is a lovelorn, excruciatingly self-conscious Russian émigré living in prewar Berlin, who commits suicide after being humiliated by a jealous husband, only to suffer even greater indignities in the afterlife.
